AI-Powered Weather Forecasting Model Aardvark Aims to Democratize Global Access
A groundbreaking international initiative has introduced Aardvark, a new AI-driven weather forecasting model that promises to deliver predictions as fast and accurate as those from top-tier public meteorological services all from standard desktop computers.
Unveiled in a paper published in Nature, the project is led by the Alan Turing Institute in collaboration with Cambridge University, the European Centre for Medium-Range Weather Forecasts, and Microsoft. The goal is to make advanced weather forecasting more accessible to resource-limited countries, particularly across Africa and other data-scarce regions.
“Aardvark’s breakthrough is not just about speed, it’s about access,” said Scott Hosking of the Turing Institute. “By moving forecasting capabilities from supercomputers to desktops, we’re opening doors for developing nations to benefit from AI technologies previously out of reach.”
Unlike many existing machine-learning models, which require substantial computing power to process initial data, Aardvark is an end-to-end system. It bypasses the compute-heavy preprocessing step and works directly with satellite data, sensor inputs, and weather station observations to produce global and local forecasts. This drastically reduces the energy and computing resources needed by several orders of magnitude.
Early assessments show that Aardvark outperforms the U.S. Global Forecast System on numerous forecast variables, despite still being in the experimental phase.
The Turing Institute team is now focused on deploying Aardvark in underserved regions, starting with West Africa. According to Amadou Gaye, a climate physics professor at Université Cheikh Anta Diop in Senegal, Aardvark could revolutionize local forecasting for extreme rainfall and agricultural planning. “It’s comparable to how mobile phones transformed access to services like banking and weather information for farmers,” he said.
The predictability of African weather systems, due to their stability compared to northern temperate zones, makes the continent ideal for “sub-seasonal” forecasts, said Richard Turner, the project lead. These forecasts ranging from four to six weeks ahead have been challenging to achieve in the northern hemisphere but hold great promise for agriculture and disaster readiness in Africa.
Despite Microsoft’s role in the project, the tech giant has no plans to commercialize Aardvark. Turner emphasized that the model and its tools will remain fully open source.
Suzanne Gray, professor of meteorology at the University of Reading, praised Aardvark’s ability to generate both global and localized forecasts directly from observational data. However, she noted that further development is needed to match the full range and resolution of forecasts typically issued by national weather services like the UK Met Office.
Still, Aardvark represents a significant leap forward in equitable access to climate forecasting, with the potential to greatly benefit communities and sectors long underserved by traditional meteorological infrastructure.
